The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
When the head gasket begins to fail, the engine may have no symptoms at all. They only begin to occur when the leak has reached an engine oil passage, engine coolant passage or the engine cylinder.
When that happens, the engine may be very difficult to start, and run roughly when idling. There may be oil or coolant leaking, and the engine may begin to overheat, or at least run hot. At this point, there may be coolant in the engine oil pan — this will look creamy and lighter in color than the oil. Also, the radiator or engine coolant reservoir may have a gurgling sound, the presence engine oil, or smell of combustion. And the check engine light will come on.
The coolant being burned in the engine will produce white exhaust that smells sweet, like engine coolant. When the head gasket fails completely, the engine will overheat within minutes of starting, will stall and then won't restart.
A failing heater core may cause the car's interior to smell like engine coolant. The smell will become worse when the heater is turned on. The engine may also begin to run hotter until the vehicle is repaired.
The worst-case scenario is the engine overheating, which can cause extensive engine damage.
If the heater core is clogged, the air that blows when the heater is turned on will not be very hot.
A failing radiator can cause the engine to run hot or overheat. Most radiators are made of metal and plastic. The plastic parts can become brittle and crack over time, causing a leak of coolant (typically green or pink in color). All manufacturers have a recommended service interval for coolant renewal. As the coolant ages, the additives breakdown and being to form solid deposits. These deposits will build up in the passages of the cooling system and will eventually clog components, including the radiator. A leaking or clogged radiator must be replaced. Some automatic transmission cars will also have a transmission cooler integrated into the radiator. Lines going to and from the transmission circulate transmission fluid to help cool the transmission in heavy duty applications such as towing or off-roading. If this integrated cooler fails, it can allow transmission fluid and coolant to mix. This will causing shifting issues in addition to overheating.
A coolant leak may be noted from the hoses. Coolant hoses can be damaged by oil leaks, or age. This will lead to swelling or cracking, it is suggested to replace the hoses before they begin leaking to avoid potential overheating.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
The two most common signs of a bad pump are leaks and noises.
Leaking water pumps can result in damage to the drive and timing belts, and cause the engine to overheat. A failed water pump can be caused by other problems in the cooling system, such as a bad thermostat, radiator or head gasket.
To effectively diagnose a coolant leak in your 2016 Hyundai Santa Fe Sport, start with a thorough visual inspection of the vehicle. Look for any visible signs of coolant pooling under the car or around critical components such as the radiator, hoses, and water pump. If you don’t spot any obvious leaks, the next step is to perform a pressure test on the cooling system. This involves using a specialized tool to pressurize the system, which can help identify hidden leaks that may not be immediately visible. Additionally, keep an eye on your coolant levels; a consistent drop in coolant can indicate a leak that needs addressing. Don’t forget to check the radiator cap as well, ensuring it is in good condition and properly sealed, as a faulty cap can lead to coolant loss. Inspect all hoses and connections for any signs of wear, cracks, or loose fittings, as these are common culprits for leaks. Lastly, be alert for any white smoke from the exhaust, which could signal coolant entering the combustion chamber. By following this diagnostic approach, you can systematically identify and address any coolant leaks in your vehicle.
When dealing with coolant leaks in a 2016 Hyundai Santa Fe Sport, it's essential to recognize the common problems that may arise. A damaged radiator is often a primary culprit, as corrosion or physical damage can lead to significant leaks. Additionally, worn-out hoses are another frequent issue; over time, these hoses can deteriorate, resulting in cracks or holes that allow coolant to escape. The water pump, responsible for circulating coolant throughout the engine, can also fail, leading to leaks if it malfunctions. Furthermore, loose or damaged hose clamps may fail to create a proper seal, exacerbating the leak problem. In more severe cases, a cracked engine block can be the source of coolant loss, which requires immediate attention from a professional. Lastly, a leaking heater core can cause coolant to leak inside the vehicle, creating both a safety hazard and a potential for further damage. Addressing these issues promptly is crucial to prevent overheating and protect your engine, making it vital for DIYers to be aware of these common causes when troubleshooting coolant leaks.
Addressing a coolant leak in your 2016 Hyundai Santa Fe Sport is of utmost urgency due to the serious risks associated with engine overheating. Coolant plays a vital role in maintaining the engine's temperature, and a leak can quickly lead to a significant loss of coolant fluid. This not only compromises the engine's ability to regulate its temperature but also increases the likelihood of overheating, which can result in catastrophic engine damage and costly repairs. Furthermore, neglecting a coolant leak can diminish your vehicle's overall performance and efficiency, leading to further complications down the road. For the safety of both the vehicle and its occupants, it is essential to tackle any signs of a coolant leak immediately. By doing so, you can prevent more severe issues and ensure that your Hyundai Santa Fe Sport operates smoothly and reliably.
